Cannabis grafting

How long are people finding it takes for a graft to really take hold (or become clearly not). Mine are on day 5 @ ~75f and might need some water, but I'm trying to not poke at them.

Ime it takes around a week, give or take. If they need water then give them a drink:). Won't hurt the grafts especially after 5 days.

Say you theoretically wanted to clean up a huge momma plant, and turn her into 2 plants, equal in size. Say she is really bushy with lots of large branches, and just air layering her in half isn't an option, because she has been monster crop trained for a year...

Would it be possible to air layer her largest branch, and instead of air layering the rest of the branches(remember only 2 plants), to cut them and graft them to the air layered branch? Basically to save alot of time.

I'm talking about grafting and air layering at the same time on the same branch, so you end up with one huge air layered + grafted plant, so that you only have 2 plants by the time you cut the air layer off.

Or would it be better to spend more time, air layer the one big branch and wait until it is potted with a good root system, then graft the rest of the donor plants branches to it (i'm talking branches almost equal in size to the air layered clone...).

Seems like a crazy idea I know, but I have taken interest lately to air layering and now grafting. I know for a fact you can layer out huuuuge clones, but haven't tried grafting yet, just seems like a cool experiment :) Can you graft numerous large branches onto a rooted out branch that is the same size?

Thanks,
Drop

You are probably wondering why I would ever attempt such a thing. The reason I wonder is because I air layered 11 or so huge clones off a gigantic mother plant that got too large to flower out. Halfway through the process a snitch sent a welfare check on me. I had to get a medical card to be safe, and while still having one plant (limit is 4 now), I had to give away all the plants except 3.

I thought about cutting the freshly rooted air layers, that had to stay potted while hooked to mom still to keep my ass safe just in case (crazy i know!), and grafting them all back on to my largest air layer haha. By then I was so tired of messing around I just gave them away, but just wondering if I could have performed my above idea in the first place, and kept them all as one plant instead.

the wedge graft

the wedge graft

5 days after cutting and it looks like this one is fine. Blue Cindy grafted onto a bag seed.

Blue Cindy veneer graft

Blue Cindy veneer graft

Grafted onto the same plant as the Kurple Guerilla. Looks just fine 5 days after cutting. Both this and the wedge graft had their humidity baggies removed today.

Alien Bubba Berry veneer graft attempt #2

Alien Bubba Berry veneer graft attempt #2

Looks a lil limp but I have high hopes as it's still alive. The Kurple Guerilla looked similar before it took so I haven't lost hope. Grafted onto the same plant as the Kurple Guerilla and the Blue Cindy. Should be an incredible mother plant if all of these take.

One out of 6 did take! Two others almost did, they still have a little hope.

The one that did best I rapped with just electrical tape. A tight rap seems to be key. As the cut surfaces callus over (not sure if that's actually what is happening) they push outward. Possibly a large amount of auxin goes to the cut?
It was enough force to open up the HPHT (hot pink hockey tape) and several I had rapped with just food cling rap.

Oops, that was actually a picture of one that might not make it. Here is the happy one. Sorry, it's not really in focus, but it's the blob on the close stem.

Love everything about these experiments! Nice work!

Regarding Exp. No. 7 (Embryo implantation): If the seed were germinated any further, do you think it would take? The newly cracked embryo went into callous mode but would anything slightly older form a bond with the cambium of the rootstock? Or would the nutrient content of the existing rootstock be too much for the newly popped seedling?

Here's my grafted monster. The root stock is a bag seed. The strains/hybrids grafted to it are Kurple Guerilla, Blueberry and Blue Cindy. The grafts are all growing strong.

I'm going to veg it out for a month or so then throw her into flower.

Hi bsgospel,
I'm not sure if it would work with a slightly older seedling... I would have to give it a try. However, at this point, it would probably be just more efficient to just cut the steem of the newly seedling above the roots and graft it to your rootstock. The idea behind the seeds embryo grafting was to bypass the plant limit legal restriction in grafting plant material that does't have any roots developpement...

On the 7 graft, 3 would be side graft on the trunk and the remaining 4 would be for transversal V-cut graft on the top:

Making the first 3 side graft cuts on the rootstock:

Inserting the 3 scions for the side grafts:

Then with the 4 additionnas grafts:

Here is an update on the 7 scions graft experiment. All 7 grafts took quite easily. Unfortunately I gave the plant away before taking any picture after its acclimatation period. :(

And now, since experiment 4 was a success (Trunk and root system fusion - post 106, 107) I decided to graft 4 more trunk for a total of 6 plants fused together. The same technique was use.

Roots base:

[URL=https://www.icmag.com/ic/picture.php?albumid=70944&pictureid=1699940&thumb=1]View Image[/url]

I did some lollipopping at the base of the plant. Then I exposed the cambium where the contact were to be made and I wrapped all trunk firmly together. I used principally LST and SupperCropping to help lower to canopy...

Here is an update on the multiple truck fusion. I should have made deeper cut in each truck to expose the cambium more and bind them tighter at the contact point. However, this plant is going to end up growing outside next summer so it would have way enough time to fuse to a single trunk. BTW, I trimmed several branch of this plant several time and kept it in a really small pot since I wanted to keep small before the summer time (lack of space).












The last picture is just a clone of a Biker Kush leaning pheno of my BikerKushX((GG4X(GSC forum cut x Arcata Trainwreck)) project. 18 female plants were selected from a 1000 seeds run. The originals plants (18) are going in flowering mode real soon! May be interesting.

Incredible post :rtfo:

Im thinking about the mantain strain (Nanda Devi for example) with a little number of plants. I want say with 2 plants, graft and have with one plant 6 plants, now 2 plants 12. So the genetic neck bottle (i dont know if it says of this form), will be better with only 2 plants.

What do you think about this?, im not so great grower and im not secure about this.

And, who be the patron...if is the male probably he dead faster or no?
May be better get all of the females and get the pollen of the male from other plant?

And finally....how are these cannatatos
:woohoo:
